Power led cable

[DeeInBetween]

I have the ASRock X370 Killer SLI/ax motherboard with the usual pin connectors. But the power led connector that came with the case is a plug in? I haven't been able to find any sort of adapter via Google. If it doesn't light up it's no biggie. Everything else runs. But I'd rather it did since the case has rgb lighting to match the rest of my build. Can anyone help me out?

What case?

If it is RGB it is either USB or intended for one of your motherboard RGB headers if applicable.
